Report microplastics occur in lower airways of European citizens with the majority being fibers; evaluate microplastics indoor and outdoor exposure sources; work out established particle domains and paradigms can help predict toxicity of inhaled microplastic particles
Global Food Contact Conference 2022: updates from Asia
Smithers conference covers global developments in food contact regulations and materials; speakers on day two review recent and upcoming changes to food packaging regulations in China, Japan, India, and Southeast Asia
Microplastics: linkage to the gut's microbiome and autism spectrum disorder
Scientific study reports that gut passages change polyethylene terephthalate (PET) microplastics morphology and alter human microbial colonic community composition; another study finds polyethylene (PE) microplastics to accumulate in the brain and induce autism spectrum disorder-like symptoms using a mouse model
Scientists explore international bisphenol levels in packaging, food, and urine
Four studies investigate bisphenol (BP) migration from packaging, occurrence in foodstuff, and human urine; report BPA migration from Nigerian epoxy-coated cans into malt drinks; detect four bisphenols in packaged water and honey samples; find BPS in Canadian meat products from 2008 to 2020 suggesting BPS is not a recent phenomenon; measure higher bisphenol alternative levels in Belgian population in 2018 than 2015
Food contact chemicals among 921 substances tied to breast cancer risk
Researchers expand list of known substances with characteristics linked to breast cancer by more than four-fold; many are in standard consumer products, including 189 in food contact according to FPF’s database on migrating and extractable food contact chemicals (FCCmigex); authors call for improved hazard identification methods, advocate for more comprehensive chemical testing, especially focusing on the mammary gland and broader range of chemicals
Science and statecraft at the second Plastics Treaty negotiation
Diplomats from across the globe descended on Paris, France to continue developing the UN treaty on plastics pollution; Scientist’s Coalition for an Effective Plastics Treaty members spoke to delegates from every continent, representing 33% of the world’s population; UN secretariat will develop INC-2 synthesis report, create zero draft by INC-3; elements for intersessional work can be submitted until August 15, 2023; INC-3 in Nairobi, Kenya in November 2023
Hazard prioritization of printing inks and adhesives substances
Scientific study performs hazard prioritization on chemicals in printing inks and adhesives applied to plastic food packaging; uses publicly available “substances of concern” lists and an in silico tool; identifies 636 high and 1024 medium priority substances of which 696 ranked as “very high priority substances” by experts
FPF Workshop 2020: Hazardous chemicals in FCMs
Stefan Merkel presents recent work of German Institute for Risk Assessment (BfR); Lisa Zimmermann discusses bioassay-based toxicity assessment of conventional plastics, bioplastics, and plant-based materials; Andrew Turner emphasizes presence of toxic brominated flame retardants in recycled plastics, uses of hazardous heavy metals in colored decorations applied to glass articles
What knowledge is missing to derive a microplastic threshold value?
Microplastic experts review mammalian in vivo effect studies and develop non-regulatory health-based screening level value for microplastics in drinking water; scientists provide research recommendations to better understand microplastic toxicity, effect levels, and potential health risks to humans and aquatic ecosystems; review discusses nanoplastics’ role in food allergy
Monomers migrate from plastics, some are EDCs
In a comprehensive review, researchers from the University of South Africa discuss the monomer migration from plastic food packaging, focusing on known endocrine-disrupting chemicals (EDCs); migration process, potential health impacts discussed
